Vision-Yet Not IR

[Mobhack]

In any case - most WW2 (and before) units have a night vision default base value already, and that is ZERO (0). In MBT, there are more, but infra-red and thermal imaging etc kit is rather rare in WW2. So they are already set at what was "realistic and historic" for 1930 to 1946.

(Unless you have some strange idea of your own as to what constitutes a night sight?)
